DUMPING-CART BODY.

SPECIFICATION forming part of Letters Patent N o. 653,546, dated July 10, 1900.

Application tiled May 22, 1900.

To @ZZ whom it may concern:

Beit known that LBENJAMIN WELLS CLARK, a citizen of theUnited States,residingatWash ington, in the District of Columbia, have invented certain new and useful Improvements in Dumping-Cart Bodies; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to a tank or body for dumping-carts, the same being an improvement on that character of sheet-metal cartbodies described in Patent No. 605,029, granted to G. W. Taylor May 31, 1898.

In the use of cart bodies or tanks of the character referred to which are suspended from an axle extending through a tube passing entirely across the body and through the sides thereof the weakest part of the structure is at the joint between the side plates and the tube. The heavy strain of the load as it swings from side to side as the cart is moved over uneven or rough surfaces tends to loosen the joints and cause leakage.`

The object of my invention is to overcome this difficulty.

To this end my invention consists in a dumpingcart body involving a tank of metal plate, a tube extending across and through' the sides of the body, and nuts on the tube having fianges riveted to the side plates.

In the drawings, Figure l is a broken section througha cart-body, its tube, and flangednuts, showing my invention. Fig. 2 is an enlarged sectional detail.

l is the tank or body, 2 the tube, and 3 the Iianged nut.

The body l is preferably made of sheet or Serial No. 17,526. (No model.)

plate steel in the form and manner described in the Taylor patent above referred to.

The tube should be about one-fourth of an inch thick, turned down at its ends to about one-half such thickness to form shoulders 4,

'and threaded for three inches, more or less,

to receive the flanged nuts 3.

The nuts are two and one-half inches, more or less, in length with flanges about thirteen inches in diameter ranging from about onefourth of an inch in thickness at their edges to aboutA one and one-fourth inches at their base.

In assembling the parts the nuts are screwed well onto the tube, which is then inserted to position in the side plates of the body, the resiliency of the plates being sufficient for this purpose. The nuts are afterward screwed outward against the plates and riveted, as shown. The thin ends of the tube are also reamed or forced out like those of boiler-tubes to cause them to engage the plates.

Having described my invention, I claiml. A dumping-cart body involving a tank or vessel of metal plate, a tube extending across and through the sides of the body and nuts on the tube having dan ges riveted to the side plates.

2. Adumping-cartbodyembracingthecombination of a tank or vessel, a tube extending across and through the sides of the'body having shoulders and nuts on the tube having flanges riveted to the side plates.

In testimony whereof I afx my signature in presence of two witnesses.
